How to Take a PCAP (Packet Capture) on an Zebra device using RxLogger and TCPDump Plugin

Story/Description: A packet capture(PCAP) needs to be taken on an MC40.

Workaround/Resolution:

1) If Secure Launcher Mode is on, it needs to be turned off by:

        a) Press the downward-facing arrow at the top of the screen near where it says               "Secure Launch".
        b) Press "Admin".
        c) Please contact your hospital administrator for this password. 
            Voalte support does not give this password out to users. 
        d) Press "Exit" at the top right of the screen. Press "OK"

When Secure Launcher Mode is off, you should be able to reach this screen.

2) Open the RxLogger app by pressing the app icon (which has the same appearance as what is shown in the top left corner of the following screen), that should bring you to this.

3) Press the "Stop" button to stop RxLogger.
4) At the top right of the screen there will be three dots, press those dots.

5) Press "Settings", which will bring you to the following screen.

6) Select the "TCPDumpPlugin".
7) In the this screen, press "Enable Plugin" and make sure the box is checked.

8) Select "Base filename", and change to an appropriate name. This one was named "test1"

        Note: Base Filename cannot contain a space.

9) Press the back button on the MC40, then press "Save" at the top of the following screen.

10) Press "Start" 

11) You will want to make sure that if you are using a Mac to have the "Android File Transfer Utility" downloaded. This can be googled and downloaded if not done so already. With Windows, nothing needs to be done.

12) Plug the MC40 into the computer using a microUSB cable.
13) The RxLogger folder should appear in the popup, in which the PCAP folder should be located. It is located at the bottom of the list here. 
-Note that the filename adds a "0" to the original, hence "test10"

*Important* - Verification that file has been created

Sometimes the PCAP file is not created and the tcpdump is not started. Verify in the file browser application that the file is created that you named in step 10 in the /sdcard/RxLogger directory.

Steps for Verifying PCAP Creation

a) Once the following screen is pulled up, proceed to press the "File Browser" icon.

b) The screen below should appear, where you can select "sdcard".

c) Select "RxLogger" on the following screen.

d) In the RxLogger folder, scroll to the bottom to find that the PCAP file is there. My file "test10" is there. Note at the top of the screen, "/sdcard/RxLogger". Typing this in the beginning is an alternative way of finding the same thing.

If it doesn't show up go back into RxLogger, stop it, and start it again. Then repeat the steps above to make sure it's running.

The PCAP will be placed in sdcard/rxlogger directory.
